SPECIFICATIONiorming part of Letters. Patent No. 6055717, dated June 14,1898.

Application filed November 29, 1897. Serial No. 660,112. (No model.)

To all whom 222& may concrn: Be it known that I, ADOLPH A. HUNZIKER,

of St. Louis, in the State of Missouri, have invented certain new andusefulImprovements in Files and Binders, of which th'e fol-A lowing is afull, clear, and exact description.

The invention relates more particularly to files and binders for aseries of separate leaves forming a ledger or other account-book; andthe object of the invention is to improve the construction of thefasteners or retainers for the leaves, Whereby the leaves may be recatecorresponding 'parts in all the figures;

Figure l is a perspective 'view of a file or binder embodying myinvention, showing acover open or thrown back to expose the leaffastening or retaining devices, the latter be- 2 is a similar Viewshowing the leaves thrown to the right and* left and theleaf-retainersopen for the removal or insertion of the leaves.

Fig. '3 is a detail perspective view showing vation showin g thefastener's and the plate or` ers or fasteners O for the ledger or otherac-- count leaves D.

The fasteners O are composed of two members c c', Fig. 3, mounted forpivot-al movement, the members being each of semicircular or' U shape orequivalent form, and they eX- tend through recesses b in the sides ofthe plate'B and meet at the under side of said plate,where they arepivotally united by a Wire 0 or its equivalent, the Wire in the instance'shown having its ends passed upWa'd through the plate Band riveted. Theplate B between the recesses b is bent upward,`a s at b', to betteraccommodate the fasteners. There is sufticient space provided inpractice at the back of the plate B to permit a pivotal move mentof thefastener members in opening and closing. At the free ends the members cc' are given such mating conformation as to cause them to engage Witheach other, Whereby they Will be held against accidental disengagement.In the form shown one member has a projection or reducedend 0 which i'sreceived by a mating recessc in the companion member and snuglyheldtherein.

With leaf-'fasteners of this description the `leaves may be cnvenientlyshifted to the right or left of the book and the leaves may be insertedand removed readily, Whereby the different leaves, if forming a ledger,for instance, may be in use by anunber of bookkeepers. The readyremoval" and replacing of the leaves is due to the fastener membersbeing pivoted to swingin their own plane instead of having a lateralmovement, as usual.

Having 'thus described' my invention, I claim as new and desire tosecure by Letters Patent- 1." A file and binder, comprising coversconnected by a back, and fasteners for the leaves arranged on one of thecovers adjacent to the back, said fasteners consisting of bent or curvedmembers pivoted together in a recess in the cover and having aninterlocking engagement at their free ends. A I r 2. The file and bindercomprisingsuitable covers, a plate fastened to one cover, and fastenersfor the leaves, composed of members of approximately U shape pivotedtogether beneath the plate and held to the latter, the free ends of thefastencr membersbeing formed to engage each other.

3. The file and binder comprising suitable eevers, :L plate fastened toone cover, and fa& teners for the leaves, eonposed of members ofapproximately U shape pivoted together beneath the plate and held to theletter, the free ends of the fastener members being formed to engageeach other, the plate being reeessed at oppesite sides and bent Upwardbetween the reeesses to aeconmodate the fastener members, and the freeends of the fastener members being fol-med to en gege each other.
